MKDQZ-400 Pneumatic Water Well Drilling Rig
Overview
The MKDQZ-400 is a cost-effective crawler-mounted pneumatic water well drilling rig purpose-built for medium-depth borehole construction. Powered by a 92kW Yuchai diesel engine and adopting DTH (Down-the-Hole) air percussion drilling technology, it delivers stable, efficient rock-breaking performance across soft soil, sand-gravel layers and hard bedrock such as granite and limestone. With a maximum drilling depth of 400m and a bore diameter range of 140–325mm, this rig is perfectly suited for rural domestic water supply, agricultural irrigation wells, foundation dewatering and small-scale geothermal drilling projects.

1. 400m Max Drilling Depth with 140–325mm Wide Bore Compatibility
This pneumatic drill rig supports a maximum drilling depth of 400 meters and adapts to borehole diameters from 140mm to 325mm, fully covering the construction demands of most residential water wells, farm irrigation wells and small industrial water projects. One unit can undertake both small-diameter deep water wells and large-diameter shallow dewatering holes, eliminating the need for multiple equipment investments for different project types.2. 92kW Yuchai Diesel Engine with Fuel-Efficient Reliability
Equipped with an original 110kW Yuchai diesel engine — a widely recognized power brand with global after-sales networks — this rig features sufficient power reserve, low fuel consumption and high durability. It maintains stable output even in high-altitude, high-temperature and dusty working environments, with easily accessible spare parts worldwide, minimizing unplanned downtime and long-term maintenance costs.3. 24T Strong Axial Lifting Force for Safe Deep Hole Operations
The main hoisting system delivers up to 24 tons of axial pulling force, which can smoothly lift the full drill string from 400m deep boreholes and effectively handle pipe sticking and other downhole emergencies. The robust lifting capacity ensures safe and efficient tripping operations, lowers on-site safety risks for construction crews, and extends the service life of drilling tools.4. 6500–9000N.m Adjustable Torque with 66–135rpm Speed Range
The main hoisting system delivers up to 24 tons of axial pulling force, which can smoothly lift the full drill string from 400m deep boreholes and effectively handle pipe sticking and other downhole emergencies. The robust lifting capacity ensures safe and efficient tripping operations, lowers on-site safety risks for construction crews, and extends the service life of drilling tools.
5. Multi-Spec Drill Pipe Compatibility for Flexible Project Configuration
The rig is compatible with Φ89mm and Φ102mm diameter drill pipes, and supports length options of 1.5m, 2.0m, 3.0m and 6.0m. Users can flexibly match drill pipe solutions according to well depth, bore size and geological conditions, avoiding extra procurement costs for additional drilling tools and improving equipment adaptability to different projects.6. Ultra-Compact Lightweight Design for Low-Cost Transportation
With a total weight of 9.2 tons, overall dimensions of 6000*2000*2550mm and a loading width of only 2.7m, the rig can be transported via standard flatbed trucks and standard shipping containers, effectively reducing long-distance logistics costs. Its compact body also adapts to drilling operations in narrow sites such as residential yards and rural village roads, expanding applicable construction scenarios.Get a quote
